Samsung 850 PRO MZ-7KE256BW - Solid state drive - encrypted - 256 GB - internal - 2.5" - SATA 6Gb/s - buffer: 512 MB - Self Encrypting Drive (SED), TCG Opal Encryption 2.0
The Samsung 850 PRO mz-7ke256bw touts itself as the next leading solid state drive for performance, endurance, and energy efficiency.
It is considered as the first SSD to use the 3D Vertical NAND architecture.
V-NAND basically stacks 32 cell layers on top of one another, instead of shrinking the cell to fit the form factors.
In this manner, V-NAND provides a higher density and a higher performance, while using a smaller footprint.
With the 3D V-NAND technology, the flash memory inside the SSD enables the ultimate performance in reading and writing.
Sequential reads are up to 550MB/s and sequential writes are up to 520MB/s.
Durability will not be a concern, as it is built to handle 150 Terabytes Written (TBW), which leads to a 40GB per day read/write workload over a 10-year period.
Security will not be a problem with the Self-Encrypting Drive technology.
It already includes an AES-256-bit hardware-based encryption engine.
It also complies with the TCG Opal v2.0 standards and Microsoft eDrive IEEE 1667 protocol.
The One-Stop Install Navigator software allows for a quick and easy data transfer from a SSD or hard disk to the 850 PRO.
And with the Samsung Magician software, one can conveniently set up, monitor, manage and maintain the SSD.
Aside from the 256GB, the Samsung 850 also has developed larger storage solutions in 512GB and 1TB. There is also a 128GB version.
The Samsung 850 PRO 256GB comes with a limited ten-year manufacturer's warranty.

What is V-NAND and how does it differ from existing technology? Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another rather than trying to decrease the cells' length and width to fit today's shrinking form factors. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND architecture.
Boost performance with an industry-leading 3D V-NAND SSD Powered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers the ultimate in read and write performance in both sequential and random aspects. This is especially impressive in the 128 GB model* that outperforms similar models on the market by more than 100 MB/s in write speed.
* 850 PRO 128 GB Sequential Write speed: 470 MB/s
Shift into high gear with the enhanced RAPID mode You can kick up the read/write performance on every capacity when you need it with the RAPID mode. Just like shifting gears in a car, Magician software gives you the option to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache, providing 1.8 times faster performance in the RAPID mode*.
* PCMark Vantage score (512 GB): 53K > 97K(in RAPID mode)
An SSD that won't quit before you do With twice the endurance of the previous model*, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle 150 Terabytes Written (TBW) which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty.
* 840 PRO: 73 TBW > 850 PRO: 150 TBW
Work longer with high-efficiency innovation The efficient, power management components in the 850 PRO enable you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO expends less energy while maintaining market-leading performance. The 850 PRO fully supports the sleep mode on the Ultrabook™, consuming only 2 m watts of power. Plus, its LPDDR2 cache memory provides higher performance while consuming 30 percent less power when active and 93 percent less power when idle than typical DDR2 or DDR3 memory.
Protect your PC from overheating with Dynamic Thermal Guard protection The 850 PRO includes Dynamic Thermal Guard protection, which keeps your PC performance safe from overheating. Dynamic Thermal Guard protection monitors and maintains the drive's optimal operating temperature with a throttle feature that automatically drops the SSD's temperature when necessary to protect your data and ensure the responsiveness you expect.
Level up to the 850 PRO simply without any hassle Using its One-stop Install Navigator software, you can migrate all the data and applications from your SSD or HDD to the 850 PRO quickly and easily. The Auto Install guide navigates you through the simple three-step process.
Plus, you can conveniently monitor, manage and maintain your 850 PRO with the Samsung Magician software, which features tools to help you maximize performance, including benchmarking, advanced OS optimization, disk health status tracking and over-provisioning (OP) settings.
Ensure each component works together seamlessly Samsung is one of the few manufacturers that actually design all the SSD components in-house and has the most experience in the SSD market. Because Samsung has intimate knowledge of every component and its parts, it can fine-tune them at each stage of development to ensure they work together beautifully. The result – enhanced performance, lower power consumption with an up to 1 GB LPDDR2 DRAM cache memory and improved energy-efficiency with the 3-core MEX controller.
